Thanks just making sure I haven't missed something,The studs on the valve cover is to aid in installation. There are 2 different lengths of the exhaust shoulder bolts. IIRC there are 2 short ones for the passenger side that don't have the center hole and threads, and one long one for the driver side with center hole and threads to attach a heat stove.
YOU GOTTA ME THEREEEEEEEEEI don't think I've ever seen nuts that weren't threaded on the inside.![]()
